面向实体的军事仿真规则提取方法研究

针对目前军事仿真系统开发中存在的军事仿真规则提取不完备的问题,在充分发挥ECA规则提取方法优势的基础上,提出了面向实体的军事仿真规则提取方法。该方法以实体状态变迁为中心,运用系统论方法,重点分析实体的环境、功能、行为、组元和结构状态,并将分析结果引入ECA规则。通过将该方法应用于装备抢修组实施抢修的规则提取中,验证了其对于提高规则的完备性与可信性具有较好的效果。     

Newsvendor problems with sequentially revealed demand information

This article analyzes a capacity/inventory planning problem with a one‐time uncertain demand. There is a long procurement leadtime, but as some partial demand information is revealed, the firm is allowed to cancel some of the original capacity reservation at a certain fee or sell off some inventory at a lower price. The problem can be viewed as a generalization of the classic newsvendor problem and can be found in many applications. One key observation of the analysis is that the dynamic programming formulation of the problem is closely related to a recursion that arises in the study of a far more complex system, a series inventory system with stochastic demand over an infinite horizon. Using this equivalence, we characterize the optimal policy and assess the value of the additional demand information. We also extend the analysis to a richer model of information. Here, demand is driven by an underlying Markov process, representing economic conditions, weather, market competition, and other environmental factors. Interestingly, under this more general model, the connection to the series inventory system is different. © 2012 Wiley Periodicals, Inc. Naval Research Logistics 2012     

军用飞机综合效能/费用评估方法

军用飞机的效能与费用是两个相互制约的因素,对两者进行科学合理的综合评估,对于军用飞机的发展和使用有着很重要的意义。在分析综合效能/费用的基本评估指标基础上,提出了在军用飞机全寿命周期综合效能/费用评估指标,重点对作战使用阶段的最佳效能/费用进行评估分析,最后给出结论。     

中国传统文化精神在抗战文学中的表现

抗日战争决定了抗战文学必然和中国传统文化保持着血肉联系,这使得抗战文学表现出向传统文化回归的价值趋向。传统文化观念中的正气、骨气、义气,以及缘、忍、孝等许多东西在抗战文学中得到了生动地表现。因此,极大地丰富了抗战文学的内容。     

供油挂车泵机油温度变化规律实验研究

通过实验研究了100 mm野战输油管线供油挂车泵运行时及停运后机油温度随时间的变化规律。采用数据拟合、回归分析等数学方法,分别研究了供油挂车泵空载和带负荷两种情况下机油温度的变化规律;针对供油挂车泵各种工作状态,分析了影响机油温度变化的主要因素,建立了温度变化数学模型。研究结果为100 mm和150 mm野战输油管线供、输油挂车泵机组模拟器的研制提供了一定参考。     

军事刑事诉讼概念研究

军事刑事诉讼既是国家刑事诉讼的有机组成部分,同时又是与普通刑事诉讼相对而言的一种特殊刑事诉讼。对国家刑事诉讼来说,二者是部分与整体的关系;对普通刑事诉讼来说,二者则是个别与一般的关系。军事刑事诉讼之所以有存在的必要,不是基于它的一般性,而是基于它的特殊性。军事刑事诉讼的特殊性主要体现在刑事诉讼主体、刑事诉讼内容、刑事诉讼程序等三个方面。     

Rubber match: a third Lebanon war

Israel and Hezbollah have applied the lessons learned from the 2006 Lebanon War and have been preparing for a future conflict with both sides aiming for a more decisive victory. With improved capabilities from 2006, future hostilities will be far more destructive. This article analyzes their performance in 2006 and the lessons they have drawn to predict what a future conflict is likely to look like. The article analyzes both parties in three categories: ground forces; rockets, missiles, and anti-armor weapons; and lastly, Israel's air and sea dominance and Hezbollah's efforts to counter that dominance. Finally, this article argues that, contrary to conventional wisdom, a large-scale conflict between Israel and Hezbollah is unlikely to become a larger regional conflict involving Syria and Iran.
